AUTOMATIC QUICK STOP SIGNAL Filed May 6, 1930 2 Sheets-Sheet 2 atfozmcag reams 01:1. 13, 1931 UNITED STATES. PATENT, -oF1-1c1-;f 1 ri PAUL WILLIAM TOYE, on NEW oanms, LOUISIANA AUTOMATIC QUICK STOP SIGNAL Application filed Kay 6,

indicate to following vehicles that a stop is to be made.

It is a further object of the invention to provide a signal of the character indicated that will operate in synchronism with the brake mechanism so that it will be energized automatically with the application of the brake. V

It is a further object of the invention to rovide a signal of the character indicated w 'ch will have. a tail light in combination therewith, so that the expense of an additional tail light will be avoided.

Further objects and advantages of the invention will be set forth in the detailed description which follows.

In the accompanying drawings,

Fig. 1 is a more or less diagrammatic view showing certain parts in section, of an apparatus constructed in accordance with the invention,

Fig. through the image hereinafter described.

Fig. 3 is a lateral sectional view through a portion of the image. 1

Fig. 4 is a diagrammatic view of the electrical connections.

Like numerals designate corresponding parts in all of the figures of the drawings.

Referring to the drawings, 5 designates the exhaust pipe of a motor vehicle, 6 an extension from the brake rod, 7 a crank arm operated by said extension, and 8 a flap valve to which the crank arm 7 is connected, and which acts to direct the exhaust pressure either out of the opening 9, or into a branch 10, according to the position that the valve -8. occupies. When the rod 6 is pulled, to

apply thebrakes, the outlet through 9 is 2 is a transverse sectional view 1980. serial no. 450,217.

closed and the exhaust pressure is directed into the branch. 10, where it passes a control valve 11, and through a goose neck 12, enters chamber 13, of the image 14. This image ma be in the form of a grotesque policeman, ,an it comprises a swinging arm 15, which is moved to the upright position shown, by the action of the exhaust pressure against a vane 17 that is connected to the arm 15. This vane is, preferably, provided with a packing strip 18, at the point where it com tacts with the curved wall 19 of the chamber 13. The arm 15, preferably, carries a hand or disc 20 at its outer end, which is provided with a red light 21, that is electrically energized automatically upon the lifting of the arm. That is to say, the movement of the arm completes the electrical contacts 22- to energize the light. The image is, preferably, provided with a tail lamp indicated at 23, which projects outwardly beyond the face of the image a sufiicient distance to permit white light rays from the underside.

thereof, as indicated at 24, to shine down upon the license plate (not shown). The face of the image may be illuminated by a light 25, placed beneath the visor of the ca 26, and this light may be controlled throug the contact 22, or may be in circuit with the tail light, whichever is preferred. The other arm 27 of the image is shaped so as tobring the hand portion thereof in front of the mouth of the image, at which point a whistle,-

horn or other noise making device, 28, is located, and whenever the arm 15 is raised, part of the exhaust gases are permitted to pass through the whistle and sound the same.

To accomplish this, the vane 17, or any other part of the arm, is connected by a link 50, with a. whistle slide 51. This whistle slide moves across the opening 52, which constitutes the mouth .of the image, and when the arm is inlowered position, the slide covers.

this opening, and when the arm is in raised position, the slide is lowered to uncover the opening. The whistle slide. comprises the front plate 53 and an integral, rearwardly divergent plate 54.. An opening is left between these plates at the top, but the plates are joined to each other at the bottom and move together under the influence of link age 50 and vane 17. Thus, the exhaust gases, or other fluid can enter between the plates at the top and pass out through the opening 55 of the front plate, and through the opening which constitutes the mouth of the image. It will be-noted that the opening 55 is an elongated one, and, thus, the whistle is caused to sound throughout a considerable period of the movement of the arm. Further, this action may be utilized to vary the tone of the whistle, as the arm moves.

In order to avoid the possibility that unduly high back pressure will be built up in the exhaust pipe when the valve 8 is moved to close the opening 9, I provide a safety valve consisting of a disc 29, which will move to the left, under the influence of sufliciently high pressure against the tension of spring to uncover ports 31 formed in the wall of the exhaust pipe through which any excess pressure is permitted to escape, the rear end of the exhaust pipe bein closed by a disc 32, which acts as a support or a rod upon which disc 29 slides, and around which s ring 30 is coiled. 'While I have chosen to 1 lustrate the figure of a grotesque policeman, having an arm adapted to be raised by the exhaust pressure, it is to be understood that the invention is not limited to this specific emobi- .ment of the invention, because, as far as .I

am aware, I am the first to provide means for directing the exhaust of a motor vehicle, un-

der the influence of the action of applying the brakes, into a warning signal having a movable part adapted to be moved by such exhaust pressure, and, consequently, I wish it to be understood that the appended claims are to be broadly construed, and that the invention includes the provision of any pressure actuated mechanism operated in conjunction with the exhaust of a motor vehicle, as herein described.

Having described my invention, what I claim is:

1. A warning signal comprising the representation of a human figure, a pivoted rigid swinging arm and a vane secured to said arm, a pressure chamber in which said vane moves, and means for directing the exhaust fluid of the motor vehicle into said chamber.

2. A warning signal comprising the representation of a human figure, a pivoted rigid, swinging arm and a vane secured to said arm, a pressure chamber in which said vane moves, and means for directing the exhaust fluid of the motor vehicle into said chamber, under the influence of the brake mechanism.

3. A warning signal com rising a representation of a human figure aving a pressure actuated rigid, swinging arm adapted to be lifted against the influence of gravity, means for directing the exhaust fluid of a motor vehicle into said figure for the purpose of actuating said arm, and an audible signal from the underside thereo operated by the exhaust pressure and coligure.

5. A structure as recited in claim 3, in com-..

bination with a tail light carried by said figure and rejecting outwardly beyond the face thereof to an extent to emit hght rays i to shine downward.

6. In a device of the character described, in combination with the representation of a human figure in the shape of a grotesque oliceman wearing a cap, of a light located neath the visor of the cap for illuminating the features of the image, a swinging arm constituting a part of the image, exhaust pressure means for actuating the arm, a red light carried by the arm and means for energizing said light when the arm islifted. A device of the character described, comprising an image in the form of a grotesque pollceman, a .swinging arm carrying a signal at its extremity, a vane carried by said arm, a pressure chamber in which the .vane moves, a fixed arm the hand of which said arm, a pressure chamber in which thevane moves, a fixed arm, the hand of which is'disposed adjacent the mouth of the image a whistle carried by said fixed arm, an

means for supplying pressure fluid to said whistle from the exhaust line of a motor vehicle, said pressure fluid being under the control of the movement of the first named arm. I a

9. A device of the character described, comprising an image in the form of a grotesque policeman, a swin ing arm, a vane carried by said arm mova le in' a chamber formed inrthe body of said image, a whistle slide adjacent the mouth of the image, a link mechanism between the vane and the whistle slide, and means for admitting pressure fluid to the said chamber to move the vane, swing the arm and to simultaneously move the whistle to permit the pressure fluid to sound the whistle.
